To all whom it may concern.'

Be it known that we, JOHN KIRBY, J r., a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, and TERANon SCULLIN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and use.

ful lmprovements in Metal Sash, of which the following 'is a specication, reference being had therein to the accompanying drawing.

This invention relates to a metal window sash and while it is designed more particularly for use in connection with railwa cars, it is capable of use in connection wit structures of various kinds.

@ne object of the invention is'to provide a simple and inexpensive metal sash which will be light in weight and of a strong durable construction which will not be easily distorted from its true shape.

lt is also an object of the invention to provide such a sash in which ordinary wood fastening devices, such as screws, may be used for attaching the glass retaining strip to the sash rail, and, further, to so construct the sash as a whole that it will fit snugly in its frame without binding.

ln the accompanying drawings Figure 1 is a front elevation of a window sash embodying our invention; Fig. 2 is a vertical sectional view taken through one of the vertical sash rails just inside of one of the members forming the rail; Fig. 3 is a transverse sectional view taken on the line of Fig. l; Fig. t is a transverse sectional view taken on the line y-y of Fig. l; and Fig. 5 is a transverse sectional view taken on the line z-z of Fig. 1. l

In these drawings we have illustrated one embodiment of the invention and have shown the same as applied to a sash designed for use in a steel railway car. lt will be obvious, however, that` the shape and style of the sash may be varied lto accommodate the same to structures of various kinds without in any way deviating from the spirit of the invention.

In that embodiment of the invention here shown the sash is made up of four sash rails, the top and bottom rails being indicated by Vthe reference numerals 1 and 2, respectively,

while the side rails are indicated by the refprovided with such channels erence numerals 3 and 4, respectively. Each sash rail preferably comprises two side members which are arranged substantially parallel one with the other and constitute the inner and outer faces, respectively, of the rail. These side members are rigidly connected one to the other but are spaced apart. One member of each sash rail, in the present instance the rear member, preferably projects inwardly a short distance beyond the edge cf the other member of the rail thus forming a support, as shown at 5, to receive the edge of the pane of glass 6. rEhe glass is secured against the supporting edges of the sash rails by means of the usual glassretaining members or strips 7, which are secured to the rails in the manner to be A .manners, we prefer that each rail should be cast in a, single piece and the rails may, if desired, differ slightly in the details of their construction. ln the particular sash here shown, each rail is provided along its inner edge with a channel or longitudinal-recess 33 formed between the two members of the rail, and the vertical sash rails, 3. and 4, are or longitudinal recesses along both their inner and outer edges, the latter being indicated by the numeral 34C. To this end the vertical sash rails 3 and L have their parallel side members connected one to the other by connecting and spacing members which are arrangedsubstantially midway between the inner and outer edges of the'rail and are here shown as a series of lugs 9, cast integral with the side members of the rail. The bottom sash rail 1 is beveled on its outer edge to conform to the sloping sill of the window frame and is provided with a longitudinal channel 10 adapted to receive a weather strip 11 which projects slightly below the edge of the/sash and engages the sill to form a tight joint. The channel l() for the weather strip is preferably formed in the rail by casting and extends the full length of the rail. The wall of the channel 10 is provided with a longitudinal projection or rib 12, arranged between the inner and outer edges of the channel, which serves to reduce the width of thej weather strip 11l is of yieldable material The and is inserted in the channel from one end intermediate portion of the channel.

j nected one to the other in any suitable man-` belng compressed to con orm it tothe shape By thus conforming the strip to the shape of the channel it is held securely in position within the same and cannot be readily withdrawn. If it should be V10 will so limit the compressibility of that pori tion of thestrip that considerable force will -be required to move it ast the projection 12.

The inner portions o the two .members of vthe sash rail are spaced apart to forin between them a channel, the bottom of this channel being formed bythe inner wall of the weather strip channel 10. The adjacent ends of the several sash rails maybe con-` ner, but it is necessary that this connection should not only be 'a very rigid, durable one,

` but that'it should be smooth and susceptible metal sashes of being practically concealed when the sash lis finished. To accomplish this we preferably miter the adjacent ends of the rails t0 form a smooth joint and'insert betweenthe side members of said rails a connecting block 16, which bridges the joint and extendswell into each rail, the block being preferably angular to permit of this arrangement. The secured in position by means of suitab e fastening devices, suchA as rivets or screws, and the resulting joint is exceedingly strong and durable and the 40 abutting edges of the rails are ei'ectually prevented from vrelative movement which would tend to break the finish on the sash.

y Thed use ofmachine screws, or metal fastemng devlces of anyv kind, to lsecure the glass-retaining strips to the sash rails of is objectionable for various reasons, such as the diiiiculty in alining the openings 1n the glass-retaining strip exactly with the threaded openings inthe rail, and the diliculty of securing the 'strip if the threads in one of the openings Iin the rail4 should become -worn or shouldbe stripped. We have, therefore, Aso constructed the sash that ordinary wood screws or.similar. fas? tening devices can be used, thus enabling a fastening'device to be placed at almost any point along the strip. To accomplish this we have mounted in the channels formed at the inner edges of the sash rails', blocks of wood, which, in the present instance, are inA the form ofvstrips 14 extending lengthwise of the respectlve sash rails and held firmly therein.V The wooden strips may be secured within the channels in any suitable manner, but in the present instance they wooden ller strips 'lng screws may v smooth outer edge of metal are seated against the bottoms of the channels and are tted snugly between the side members of the. rail, which serves to hold them in position. The Wooden strips, 0r blocks, terminate substantially ush with S70 v the inner edgefof the front or narrower members of the respective sash rails, so that when tl1e` glass has been placed in. position y the glass-retaining strips will rest upon the glass closefto the edges of the' respective A and lthe fesual fastenbe passed through the retainmgstrips. into the filler strips, in substantially the-same manner as is done with wooden sash. In the case of the vertical l80 sash rails, 3 and 4, the bottoms of the channels are formed by tle connecting lugs 9, and in the bottom sash' rail, the wall of the weather strip channel forms the bottom of the inner channel for the lle'r strips. The upper sash rail 2 is here shown as having a and as it is unnecessary that the wooden filler strip should ofa width equal to the width f the rail,

we havel provided a series of lugs 15 which .90

project into the channel from the inner wall L 4 thereof and serve to limit the inward movement of the filler strip, thus enabling-a narrow strip to be used. L In addition to enabling wood screws to be used for the glassretaining'strips, the wooden ller strips also serve to reinforce the respective sash rails and to prevent the metal from being `bent or indented, thereby rendering the sash less liavf 3 ble to be distortedin ordinary service.'`

Itl has been found in practice that window openings in steelcars and similar structures are liable to vary slightly in their widths,`and inasmuch as the metal sashes are made to standard dimensions, diiliculty is sometimes experienced in securing the Ifoper fit between the sash and the window rame. Further, the walls of the Window frames which form the guideways for the` sash are not always true andthis sometimes results in a sash that does not fit properly or is not weathentight. j To overcome these difficulties and enable the standard sash to l be accuratelyv tted into the openings designed to receive it, even though these openv ings may vary slightly in their dimensions, we have made the width of vthe sash adjustable. To accomplish this, onel or both of the y vertical sash rails are provided with longitudinal channels` along their outer edges and suitable frame engaging members are moun d in these channels. As here shown,I the right hand vertical rail, 3, has mounted therein a metal frame engaging member in the form rof a bar 17, which extends for sub- 125 stantiallythefull length of the sash rail and is ca able of bodily movement transversely o the rail. "T0 this en'd it is held within the rail by means of pins 18 extending through the same and through slots 19 130 the desired Width.

edge of -in practice that one part ter, even though the means of springs 20. In the present 1nstance these springs are curved leaf spring s and are placed'loosely between the ar 17' and the inner Wall of the channel, which is formed by the-lugs 9. The longitudinal movement of the springs is limited by inwardly extending lugs or ribs 21, which serve to retain the springs in their lproper relative position. The number and character of the Springs will depend in a measurey upon the character and size of the sash. In the present instance we have employed three springs. fIt will be obvious that this yieldable frame engaging member will enable the sash to it snugly within sash open Aings differing somewhat in width, and always maintain a tight joint between the the sash and the window frame.

Further, this bar is preferably of such a character that it will accommodate itself to irregularities in the guideway of the window frame. For this purpose the bar is more or less flexible and it has been found of the bar can be compressed without affecting the positions of the other parts thereof. For example, the central portion of the bar can be bent inwardly a considerable distance while both ends will remain in their original positions. rlhis flexibility, combined with the yieldability of the bar as a whole, enables it to fit snugly within the guideway and to form a tight joint throughout the length of the latguideway is not true. lf desirable to provide a greater range of adjustability of the sash than that which can be had with the yieldable frame engaging bar 17, this may be accomplished by providing the other vertical sash rail, (l, with an outer, channel in which is secured a bar of wood or similar material, 22, which will project beyond the outer edge of the rail and which can be dressed down with a plane or other implement to give the sash In the present instance, where it is desired to secure a large range of adjustability we have employed both the yieldable bar and the wooden bar, but it is obvious that either can be used without the other. Further, vit will be apparent that both bars iit snugly between the side members of the rails and reinforce the same against bending or denting.

In order to provide the sash with adequate lifts without forming thereon handles which would project in front of the sash a distance sufficient to interfere with the cur-v tain, We have formed the lifts integral with the upper and lower rails, respectively, and to this end have cast in these rails recesses, 23, along the upper edge of which is a projection or lip 24 which extends but a short distance in front of the rail, but which when -sired point along the combined with the top wally of the recess 23 provides a large and ample finger grip.

It will be apparent from. the foregoing description that we havevprovided a metal sash of very simple construction and of a very rigid and durable character, which can be adjusted to accommodate it to variations in the width of the window openings and which will automatically accommodate itself to irregularities in the guideway of the window frame. Further, it will be appar- 'ent that the glass-retaining strips may be secured to thessashrail with ordinary Wood screws which may be inserted at any delength of the strip; that the metal parts of the sash are so reinforced that they will not be readily bent or indented; that 'the weather strip at the lower edge of the sash is secured thereto in such a manner asv to effectually prevent displacement and that the lifts are of a relatively large size affording an ample finger hold, but are so built into the sash rail that they project but a short distance beyond the face of the sash.
